Bug 116499 – app-emulation/qemu-softmmu-0.8.0 - executable stacks

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Michael Cramer 2005-12-23 08:49:02 UTC]

QA Notice: the following files contain executable stacks
 Files with executable stacks will not work properly (or at all!)
 on some architectures/operating systems.  A bug should be filed
 at http://bugs.gentoo.org/ to make sure the file is fixed.
RWX --- RWX usr/share/qemu/proll.elf

[Comment 1 Luca Barbato 2005-12-23 13:25:50 UTC]

false positive, sorry

Re-assigning...

/usr/share/qemu/proll.elf lacks a PT_GNU_STACK marking thus ld.so will load this 
as eXecutable on everything but PaX enabled systems.

[Comment 4 solar (RETIRED) 2005-12-26 08:35:52 UTC]

Which is probably also correct that it be loaded as eXecutable seeing as it has a 
RWX PT_LOAD which is even worse.

[Comment 5 solar (RETIRED) 2005-12-26 08:38:17 UTC]

That binary seems to not be built using a gentoo system. poking at the ELF 
innards we can see it was built with GCC: (GNU) 2.95.4 20010319 (prerelease)
which probably explains the crappy PT_LOAD segment.
Anyway this bin can be built on a gentoo system? Is it a binary only elf?

if your package actually needs executable stacks, you can put 'RESTRICT=stricter' in your ebuild and it will not abort

but as to whether this is such a case, i dont know as you didnt really explain why this is a "false positive"

>=0.8.2-r1 is using the QA_* variables to supress these warnings, and that's about it. Closing.
